About Bell Metallurgy and Mark Bell


"I've never met a machine I didn't like."

In 1984 I started consulting on a full time basis. Since then there are many satisfied people who have used my skills to solve problems. Feel free to contact me for an initial discussion, no cost. It is my pleasure to help you. I have always prided myself with good customer service. Unbiased opinions, good personal contact, listening to your needs and using the best metallurgical tools to complete the assignment in a timely manner is what I offer. I enjoy what I do. I can help to solve your problems.

Components are shipped to my laboratory or I am available for travel.

People ask about my logo. It is a dendritic crystal growing in all three directions. Metals are crystals. Metals are useful as engineering alloys because of their crystalline structure. The good properties of ductility, malleability, ability to conduct both heat and electricity and its good strength are based upon the order and alignment of the crystal structure. My logo is showing the perfect three dimensional growth of a phase of a metal as it solidifies under perfect conditions. The art and science of metallurgy is based on the understanding of the crystalline nature of metals and their alloys. The wonderful engineering alloys we use in every part of our lives are based on understanding how to control and modify the crystalline nature of metals.

I look forward to hearing from you,
